One way to fix a mess is to have Maple re-execute the whole worksheet (look on the Edit menu). This works best if old expressions are cleaned up first, so it is a good idea to start each worksheet with the command restart; You do not need to do so of course . ... > restart; Maple commands are executed by pressing the Enter key when the mouse cursor is in the line containing the commands.

You can also stack up several commands on one line by terminating them individually with colons or semicolons. The effect of the colon is to suppress output from the corresponding command, though the command is still carried out. All the commands on a line are executed when you press the Enter key.
